네트워크 트래픽의 응용 별 분류는 최근 학계의 중요한 이슈 중 하나이다. 기존의 전통적인 트래픽 분류 방법으로 대표되는 well-known 포트 기반 분류 방법 및 페이로드 시그니쳐 기반 분류 방법의 구조적 한계점을 극복하기 위한 새로운 대안으로써, 트래픽의 상관관계를 통한 분류 방법이 제안되었다. 본 논문에서는 트래픽 상관관계에 대한 정형화된 식이나 룰을 찾는데 유용한 정보를 제공하기 위해 인터넷 응용 별 트래픽을 동작형태의 관점에서 분석하였다. 학내 망에서 자주 사용되는 인터넷 응용을 선정하고, 이들이 실행 초기에 발생시키는 트래픽을 플로우와 패킷 단위로 분석한 내용을 기술하였다. 특히, 인터넷 응용이 발생시키는 플로우 중 페이로드가 존재하는 첫 플로우를 first talk 라 정의하였으며, 이에 대한 상세한 분석 내용을 기술하였다.

This study takes note on the need for the consideration of the relationship between the service contents and service space which libraries provide, since at the moment the demands of library users, purpose of using it, etc. gradually become varied. In this study, type classification of public libraries was done focused on the relationship between service contents and service space, targeting Japanese public libraries. Through linking approach between service contents and service space, the analysis of Japanese public libraries' characteristics and type characteristics could be captured. This study has ultimately aimed to prepare for the basic data which will help Korean public libraries to make connection between service contents and service space in the future. The collected service contents and service space had been analyzed by multi-dimensional data analysis methods such as the "Quantification Theory Analysis Type III" and "Cluster Analysis". After characters of libraries were analyzed, the findings of this study show the views such as "the field of information provided, the method of information provision, and the object of service provision." And types of 44 libraries are classified into those which have 6 kinds of characteristics as follows : (1) group-oriented libraries which provide the jobs and employment information, (2) libraries which provide the jobs and employment information through the counselling space, (3) individual-oriented libraries which provide the information of education-related fields, (4) group-oriented libraries which provide the information of education-related fields, (5) libraries which provide information focusing on the counselling space, (6) individual-oriented libraries which focused on the service provision.

In this study, the information literacy educational program currently used by Korean universities was applied to foreign ones and its educational effect was analyzed and their degree of satisfaction and demands were understood. As a result, the educational effect was shown, but the average knowledge of academic information used still remained low, but the satisfaction degree of education for information literacy was high, which means that such education is absolutely needed for foreign students. The analyzed results and contents carried out in the experiment will be very helpful for designing a differentiated information literacy educational program for foreign students.

앞으로 다가오는 정보화 사회에서의 국가경쟁력을 키우기 위해서는 정보처리 및 운영능력이 대단히 중요하다. 지리정보는 이러한 정보화 사회에서 중요한 국가 간접자본중의 하나이다. 그리고 국가 GIS에서 가장 풍요한 요소는 지리정보의 호환, 공유, 유통 등을 포함한 지리정보의 활용이다. 따라서 국가적으로 GIS의 활성화를 위하여 지리정보의 표준화가 시급한 실정이다. 이 논문에서는 국제 표준화 기관인 ISO/TC211에서 수행중인 표준화 내용을 분석한다. 특히, 지리정보의 활용과 GIS들간의 상호 연동성을 위한 지리정보/지리공간 서비스를 중점으로 하여 IS0/TC211에서 표준안으로 제시하는 서비스 항목, 인터페이스 등 지리정보 서비스와 관련된 내용을 분석한다.

뉴스나 드라마, 영화 등의 비디오에 대한 검색 시 일반 사용자의 요구에 가장 잘 부합되는 결과를 얻기 위해 비디오 데이터의 의미적 분석과 색인을 만드는 것이 필요하다. 일반적으로 음성신호가 비디오 데이터의 내용을 잘 나타내고 비디오와 동기가 이루어져 있으므로, 내용기반 검색을 위한 비디오 데이터 분할에 효율적으로 이용될 수 있다 본 논문에서는 캡션 정보가 주어지는 방송뉴스 프로그램을 대상으로 효율적인 검색, 색인을 위한 비디오 데이터의 분할에 음성인식기술을 적용하는 방법을 제안하고 그에 따른 실험결과를 제시한다.

To understand the present states of abstracting and to investigate contents of abstracts, a survey content analysis was done in the field sciences. Of the 102 nation wide scholarly journals examined $54(53\%)$ included abstracts with articles. 33 had abstracts in Korea Among the 34 journals with editorial statements about abstracting only 13 had suggestions about abstract contents. Based on the investigation, 4 disciplines having abstracts mostly was selected and 149 abstracts in the 4 major journals in each discipline were sampled. Complete abstracts were ama;uzed according to 12 variables covering required content elements, unnecessary statements, and writing styles. Statistical characteristics of the abstracts is varied among disciplines and the scope is very wide. Particularly number of paragraph and number of character per abstract is much different from the standards. The content analysis showed $51\%$ of the abstracts were incomplete. $39\%$ of the abstracts did not mention research method used. 59 abstracts included unnecessary statements. Writing stle analysis also showed many faults both in the pronoun abuse and the misuse of voice or tense. Korean author abstracts in social science scholarly journals have deficiencies in linguistic structures as well as in contents and style.

The purpose of this study is to examine the emotional and behavioral characteristics of information seeking of university students in context in which a class assignment should be completed. An attempt was made to understand better individualized and selective behavior observed while seeking information in the commonly defined context. Data was collected from content analysis of self-reports by 54 university students majoring in library and information science. Major findings were analyzed in relation to the preception and feelings over, and barriers and strategies of seeking information, and the use of information resources.

Existing methodologies of technology planning about promising new technology focused on target technology itself, so it is true that socio-environmental context which the relevant technology has influence on is not well understood. In this respect, this study is aimed to questingly examine that news content analysis methodologies widely available in the field of science communication can be applied as a complementary methodology for contextual understanding of socio-environment in terms of technology planning about promising new technology. In the co-evolutionary environment of technology-society, promising new technology shows hype phenomenon regarding the relation with the society. Based on this, this study performed news content analysis and examined if the consequences of analysis would match hype cycle. It tried to explore substantive content understanding by socio-environment factors according to specific news frame content. To do this, new content analysis was performed targeting cloud computing as a representative promising new technology. The result of news content analysis targeting general newspapers, business news, IT special newspapers revealed that the tendency of news reporting matched the trend of hype cycle. Particularly, it was verified that reporting attitude and news frame analysis provided useful information to understand contextual content depending on social, economic, and cultural environment factors about promising new technology. The results of this study implied that news content analysis could overcome the limitation of technology information analysis focusing on academic journal patent usually applied for technology planning and could be used as a complementary methodology for understanding the context depending on macro-environment factors. In conclusion, application of news content analysis on the phase of macro-environment analysis of technology planning could contribute to the securement of mutually balanced view in the co-evolutionary perspective of technology-society.
